Cutting Edge Diagnostics

The diagnostic tool for heavy equipment

TestBox directly diagnoses transmission problems for on- and off-road heavy vehicles.

How Our TestBox Works

With TestBox we can directly diagnose transmission problems for any on- and off-road vehicle and verify whether a transmission is performing properly by measuring sensors and solenoids, and displaying the results on an easy-to-read screen.

If the issue is due to bad sensors, connectors, harnesses or solenoids, our TestBox allows us to override the OEM controls to the transmission and move the stalled heavy equipment off the road or to a nearby garage, saving you time and money.

Client Testimonial

One of our truck-mounted cranes was stalled. This truck has a MD3060 Allison transmission that we could not get to run. It was explained to me that the TestBox is a diagnostic tool that works on many different makes and models of transmissions, including this truck’s transmission.

The TestBox went through the automatic solenoid checks and shifted the transmission through its gears. Apparently, the transmission was working and the problem was coming from the truck’s electronics.

With the TestBox, this non-operating truck was actually driven to a nearby crane shop, where they could fix it.

We Dynotest all of our remanufactured units.

Transmissions and torque converters are tested under application conditions using a load cell, and all transmissions are electronically calibrated during the dynotest. Hydraulic, electro-hydraulic and electronically controlled valve bodies are also tested on our specialized test stands.

Our clutch simulator enables us to dynotest many of today’s automated transmissions that utilize a dry clutch assembly. We have even adapted our test stand to dynotest various axle and transfer case assemblies to ensure reliability and functionality.

Many of our customers see the benefit in knowing that a fully dynotested unit is going to calibrate and operate flawlessly in their machine.

As the workshop manager for TD HAULAGE, if I could give more than 5 stars for this company I would, Fred and the team have been an absolute pleasure to deal with over the years completing various rebuilds on our Allison, ZF transmissions and also Russian Balarus transfer boxes. With extreme tight time frames and strict budget costs Fred and the team have not disappointed, we have had at least 8-10 rebuilds and not one have failed since. Highly recommend for anyone in need of assistance or work completed on their own vehicle or fleet vehicles.

We have used Trans Rebuilding Centre to rebuild our Heavy Quarry equipment, our ADT40 dump truck transmissions, plus our D85 bulldozer trans and torque converter x2. The workmanship and service with getting parts was excellent. They even recond our toy cars C4 trans.

I have owned and operated over 30 fishing vessels over the last 40 years. Transmission & Component Rebuilding Centre LTD rebuilt the main gearbox for my fishing Longline vessel Sidina last year in 2021. I would like to say that Fred and his team were very helpful and accommodating. With the highest professional level of their service made this complicated job at ease for me and the work and rebuild completed has been very successful. I definitely would highly recommend this company to anyone who needs these services.

The fishing company Tasman Harvesters Ltd would like to express their deepest gratitude to Transmission & Component Rebuilding Center Ltd for the repair of the main gearbox on the f/v Seamount Enterprise. The work was done at the highest professional level and in the shortest possible time. We wish success and prosperity to this company and highly recommend!

We have used transmission and component rebuilding multiple times over the last few years to rebuild several transmissions including Komatsu d85, 2of ZF 6 WG310 for dump trucks, ZF 16 s manual with retarder for man trucks. We have also had multiple torque converters overhauled and they have helped us by rebuilding broken drive gears that are no longer available Fred and the team always do work to our satisfaction and are awesome to deal with.

Fred is a problem solver. The word ’can’t’ is not in his vocabulary. We have thrown him some curly ones and he has always delivered. This, along with a very friendly and courteous attitude makes for an unbeatable combination. He has rebuilt 2x torque convertors and 2 complete transmissions for our Komatsu bulldozers and this was after we were told the transmissions couldn’t be fixed. They are both hard at work and haven’t missed a beat. Very impressed. See you next time Fred.

Fred and his team offer awesome service and went out of their way to get things done in the timeframe we gave them. They are always friendly and willing to go the extra mile. In my eyes they are Superstars and I would highly recommend them!

Fred and team have been marvellous support to the Porter Group of companies for many years now throughout NZ, often parts and components to repair or overhaul transmissions and drivelines can be expensive or hard to source, T & C rebuilding Centre have often provided the solution and very economically, fantastic service, recommend to all.
